LSFG is an advanced frame generation tool based on Lossless Scaling technology.
It enables real-time frame multiplication (X2, X3, X4) using LSFG 3.0, 3.1, and 4.0 algorithms for massive FPS boosts.
The project supports AMD FSR, NVIDIA NIS, Integer Scaling, and Vulkan integration through lsfg-vk.
It is optimized for Windows 11, Linux, and especially Steam Deck with Decky Loader plugin support.
Perfect for gamers seeking higher frame rates, smoother gameplay, and low latency in modern titles.
